This is in addition to 50,000 laptop batteries that were previously recalled.

HP has discovered additional laptops that may contain defective lithium-ion batteries that pose a risk of overheating and catching fire. The new total now stands at 128,500 batteries, as part of this recall.

According to a notice posted by the US Consumer Product Safety Commission (CPSC), HP had recalled 50,000 batteries in January 2018. This latest expansion adds another 78,500 batteries to the mix.

The expanded list was actually announced by HP in January of this year, but went largely unnoticed because of the government furlough, which prevented the CPSC from posting it as well.

Since the original recall, HP said it has received eight new reports of battery packs overheating, melting, or charring, one of which resulted in a "minor injury" and two others that caused property damage totaling $1,100.

HP has put up a website where owners of its laptops can download a battery validation tool to see if they are affected. The batteries are not user-replaceable, however HP is providing free replacements through authorized technicians.
